Electrical Impedance Tomography Lung Imaging Method Based on 3D Accelerometer

Abstract

The invention discloses an EIT (electrical impedance tomography) lung imaging method based on a 3D accelerometer. The method comprises steps as follows: posture position information of a to-be-detected person is collected by the 3D accelerometer in real time and is transmitted to a controller of an EIT lung imaging system together with current electrode information; the controller judges whether the position information is changed according to the posture position information, and when the position information is changed, new position information is input into an image synthesis model, so that a new image synthesis algorithm is obtained; the currently collected electrode information is input into the new image synthesis algorithm, an image file is formed, finally, the image file is processed, and a tomographic image of the lung function is obtained and displayed by a terminal. The 3D accelerometer is adopted to collect the posture position information in real time, so that a doctor is not required to input related posture information manually and frequently; besides, the calculating accuracy of the 3D accelerometer is high, accordingly, continuity of an intensive care process is guaranteed, and the problem of inaccuracy caused by the fact a patient changes the posture himself in a long-term intensive care process is solved.

Description

technical field

[0001] The invention relates to the field of electrical impedance tomography lung imaging system, in particular to a 3D accelerometer-based electrical impedance tomography lung imaging method. Background technique

[0002] Bioelectrical impedance imaging technology uses the electrical characteristics and changes of biological tissues or organs to extract biomedical information related to pathological conditions. It is a new generation of functional imaging technology that has emerged in the past 20 years after morphology and structure imaging. , continuous, no radiation, fast response, low cost and so on. The principle of bioelectrical impedance tomography lung imaging system is to inject weak alternating current into the human body, and the current will flow along the path of least resistance, thus forming a potential on the surface of the body, using electrodes to continuously measure the potential, and then converting it into the lung function tomography....
